<h2>Mypy 1.6</h2>
<p><a href="https://mypy-lang.blogspot.com/2023/10/mypy-16-released.html">Tuesday, 10 October 2023</a></p>
<p>We’ve just uploaded mypy 1.6 to the Python Package Index (<a href="https://pypi.org/project/mypy/">PyPI</a>). Mypy is a static type checker for Python. This release includes new features, performance improvements and bug fixes. You can install it as follows:</p>
<pre><code>python3 -m pip install -U mypy
</code></pre>
<p>You can read the full documentation for this release on <a href="http://mypy.readthedocs.io">Read the Docs</a>.</p>
<h4>Introduce Error Subcodes for Import Errors</h4>
<p>Mypy now uses the error code import-untyped if an import targets an installed library that doesn’t support static type checking, and no stub files are available. Other invalid imports produce the import-not-found error code. They both are subcodes of the import error code, which was previously used for both kinds of import-related errors.</p>
<p>Use --disable-error-code=import-untyped to only ignore import errors about installed libraries without stubs. This way mypy will still report errors about typos in import statements, for example.</p>
<p>If you use --warn-unused-ignore or --strict, mypy will complain if you use # type: ignore[import] to ignore an import error. You are expected to use one of the more specific error codes instead. Otherwise, ignoring the import error code continues to silence both errors.</p>
<p>This feature was contributed by Shantanu (PR <a href="https://redirect.github.com/python/mypy/pull/15840">15840</a>, PR <a href="https://redirect.github.com/python/mypy/pull/14740">14740</a>).</p>
<h4>Remove Support for Targeting Python 3.6 and Earlier</h4>
<p>Running mypy with --python-version 3.6, for example, is no longer supported. Python 3.6 hasn’t been properly supported by mypy for some time now, and this makes it explicit. This was contributed by Nikita Sobolev (PR <a href="https://redirect.github.com/python/mypy/pull/15668">15668</a>).</p>
<h4>Selective Filtering of --disallow-untyped-calls Targets</h4>
<p>Using --disallow-untyped-calls could be annoying when using libraries with missing type information, as mypy would generate many errors about code that uses the library. Now you can use --untyped-calls-exclude=acme, for example, to disable these errors about calls targeting functions defined in the acme package. Refer to the <a href="https://mypy.readthedocs.io/en/latest/command_line.html#cmdoption-mypy-untyped-calls-exclude">documentation</a> for more information.</p>
<p>This feature was contributed by Ivan Levkivskyi (PR <a href="https://redirect.github.com/python/mypy/pull/15845">15845</a>).</p>
<h4>Improved Type Inference between Callable Types</h4>
<p>Mypy now does a better job inferring type variables inside arguments of callable types. For example, this code fragment now type checks correctly:</p>
<pre lang="python"><code>def f(c: Callable[[T, S], None]) -> Callable[[str, T, S], None]: ...
def g(*x: int) -> None: ...
<p></tr></table>
</code></pre></p>
